' Application filed October 13, 1923. Serial No. 668,369.

To all whom it mag concern:

Be it known that we, GEORGES MORIN, a citizen of the Republic of France, and lvIAno PIARD, a subject of the King of Great Britain, and residents, respectively, of Passburg and Bellevue, both in the Province of Alberta and Dominion of Canada, have invented certain new and useful Improvements in Can Openers, of which the following is a specification. V

This invention relates to improvements in can openers and particularly to can openers of the drag knife type adapted to provide, in combination with the ridge of the can, fulcrums, affording a special wedging grip in drawing the knife.

Further objects are the provision of an eflicient and economically constructed can opener of this character in which the several parts are designed to more satisfactorily perform the various functions requlred of them.

With the foregoing and other objects in view, the invention consists essentially in the arrangement and construction of parts described in the present specification and illustrated by the accompanying drawings that form part of the same.

Referring now to the drawings, in which like characters of reference indicate corresponding parts in each figure,

Figure 1 is a perspective view of the can 1 opener with the knife inserted in the top of the can, the latter being shown in dotted lines.

Figure 2 is a side elevation of the device in actual use.

Figure 3 is a front veiw of the device in actual use.

Figure 4 is a plan view.

In the drawings, A designates the device as a whole comprising a suitable shaft 10 provided with handle means 11. The shank 10 is preferably, as here shown, of hardened steel and is fitted at its outer projecting end with a plate 12 at right angles thereto and provided with a V-shaped notch 18 on the underside adapted to engage with the ridge 14 of a can or the like 15. The plate 12 is also provided adjacent the shaft 10 with a rectangular opening 16.

17 is the knife member formed with a horizontal top edge 18 and a curved lower cutting edge 19 terminating in an inwardly extending point 20, the other end of the member 17 being substantially cam-shaped and provided with a circular opening or hole therethrough 21. The knife is swingingly mounted in the rectangular hole 16,

that portion of the knife between the lower edge and the hole therein 21 being designed to swingingiy engage with the rectangular hole 16, said knife being provided with a slit 16 extending from the hole 21 to its outer edge 20'to permit its engagement with the plate 12.

In manufacture it is not necessary that a slit be provided permitting engagement of the knife with the plate 12 as the knife is intended to be enclosed, in manufacture,

between the contiguous parts without the necessity of a slit or its insertion/- In operation, by outward pressure the can is pierced, the point of the knife being so shaped as to retain it under the can-top in the process of cutting; the notch 13 is then placed astride the can ridge 14. Pressure exerted by the hand in a backward direction causes the notch 14 to securely grip the can ridge and the shank 10 to rotate about the fulcrum formed by the notch at the engaging point with the can ridge, thus drawing the knife and cutting the can. A movement of the shank forward disengages the notch 14 and for successive cuttings the notch is successively removed to further or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

What we claim as our invention is: 1. A can opener of the character described comprising, a shank member having suitable handling means and provided at one end with an orificed plate extending at right angles thereto and adapted to engage with Y I the ridge or edge of a can, a blade formed with an orifice therein and having a curved cutting edge on the underside terminating in an inwardly extending point, said plate and blade having a pivoted connection at their respective orifices.

2. A can opener of the character described eon'lprislng a suitably handled shank, a In Witness whereof We have hereunto set bladesupportmg plate, havlng an orlfice our hands 1n the presence of two wltnesses.

therein, on said shank, and formed With GEORGES MQRIN a slot to straddle the ridge of a can or MARC PIARD w v 1 v f the lnle, a blade llavlng an ounce therem adapted to form, a pivotal connection be- Witnesses: tween it and said plate sa1d blade havlng 'AGNES MAR UIS, a plerclng polnt and cutting edge.
